1. An inlet air dynamics (IAD) characterization control system for an internal combustion engine, comprising:

  • a first module that estimates a future firing event manifold absolute pressure (MAP);

    a second module that determines a MAP cycle difference based on said future firing event MAP and a previous cycle MAP; and

    a third module that characterizes an IAD state based on said MAP cycle difference.
